Which Formulas have this format?

[[V]]

Can you please give me any physics related formula that appears in this format?

$$\frac{x^2}{4}$$

Its part of a really crazy proof I am trying to do. The variables are irrelevant. Anything that looks like this would be fine!

Thanks!

How about the area of a circle

$$A = \frac{{\pi {d^2}}}{4}$$

Or it could be , the Rotational Kinetic Energy of the body :

Where K is the modified Moment of Inertia for the body.

I think the question referred to a string of char="$$\frac{x^2}{4}$$" (obviously (x/2)**2). Some clever people can somehow turn such strings into beautifully formatted maths formula on a webpage formatted 'on the hoof' and not displayed as images.

Please can some explain how to do this as I wish to put maths equations on web pages.

This format is known as a fraction or ratio format, where the numerator (top number) is divided by the denominator (bottom number). In physics, this format is commonly used to represent equations involving units, such as velocity (\frac{distance}{time}), acceleration (\frac{change in velocity}{time}), and force (\frac{mass \times acceleration}{time}). An example of a formula that appears in this format is Newton's second law of motion: F = ma, where force (F) is equal to mass (m) multiplied by acceleration (a). Other examples include the equation for work (W = Fd), where work (W) is equal to force (F) multiplied by distance (d), and the equation for electric current (I = \frac{Q}{t}), where current (I) is equal to charge (Q) divided by time (t).
